This particular inscribed copy of De La Caisse d'Escompte may have been used as the model for the one shown in the painting. Note the discoloration where the front page was exposed because of an ill-fitting cover, and the old crimp in the upper-right corner of the first page that matches the one in the painting.

The research team has collected more than 400 rare artifacts
(18th-century documents, books, pamphlets, newspapers, and other
items) related to this project, including eight original editions of Mirabeau's De la Caisse d'Escompte, the 1785 book depicted in the
portrait.1 If Thomas Jefferson is indeed the subject, one of those books—an
inscribed copy purchased from an antiquarian bookseller in Paris, France in July
2004—may be the very one shown
in the painting.

There are three reasons for considering this speculative
possibility, and for wanting to bring it to the attention of other researchers.

Pencil
inscription in back of book.

The copy
in question has a pencil inscription—"La 12 juillet 1785" [12 July
1785]—on the rear flyleaf. That was the date that Mirabeau's
colleague Benjamin Franklin left from Passy, France with his two
grandsons2 to
return to the United States, leaving some books for Jefferson.3 Jefferson's French valet "Marc" delivered the books from Franklin's Passy residence
near Paris to Jefferson in Paris. Marc may have written the inscription,
but the research team has been unable to determine his last name or find a
sample of his handwriting.45

The original cover of the
inscribed book
is "ill-fitting" in a way that matches the cover on the book shown in the Delapierre
portrait. Although the inscribed book was preserved by pasting a blue paper
cover on top of the original temporary paper cover, probably in the 19th or early 20th century, the outline of the original cover can be
seen through the preservation cover. Also, the first printed page of the inscribed
book is faded along the bottom and right edges—consistent with those
edges being exposed prior to the addition of the preservation cover. No
other original (uncut) version of De
la Caisse d'Escompte found by the research team has this particular
distinctive appearance.6

The original paper cover of the inscribed book was stamped on the outside with
a caption7 that
includes the words "A PARIS [in Paris]…P.G. Simon…." P.G.
[Pierre-Guillaume] Simon was a prestigious printer and book binder ("Imprimeur
du Parlement") in Paris when this book was published. Because De la Caisse d'Escompte is known to
have been printed in Bouillon (Belgium) and then smuggled into France,8 knowing that this particular copy was handled in Paris by the P.G. Simon
firm is consistent with it being one that Franklin or Jefferson might have
obtained there.9

A very old crimp in the upper-right corner of the first page of the inscribed book and a very old crimp in the lower-right corner of the second page of this book—both of which are features depicted in the 1785 portrait—are consistent with the possibility that the inscribed book was used as the model for the book shown in the painting. However, because this type of damage could easily occur to any old book, these flaws by themselves are not strong evidence that the inscribed book is the very one depicted. On the other hand, had these flaws not existed in the inscribed book, the research team would have used that observation to eliminate the book as a likely candidate for the exact one depicted in the painting.

References and notes

[1] For
books (actually "pamphlets") of this sort, typically no more than 800 were
printed—and usually far fewer. (Source: private correspondence
with Dieter Stecher, rare book dealer in Egelsbach, Germany, 13 October
2009.) Although we do not know how many copies of this particular title
were printed, the research team found no evidence of a second edition.

[2] Benjamin Franklin's
grandsons were William Temple Franklin and Benjamin Franklin Bache. The former served as Benjamin
Franklin's private secretary during the French mission. Benjamin Franklin, upon
returning to America, organized his massive book collection using a system of
"shelf marks." These were written in the books in two different
hands—probably by his grandsons (see "Poor
Richard's Books," compiled by James Green, 1990, p. 10). Many of
Franklin's shelf-marked books are now possessed by The Library Company of Philadelphia.
Analysis there on 27 September 2010 by Librarian James
Green—comparing the handwriting in the inscribed edition of De la Caisse d'Escompte with the
handwriting used to inscribe the shelf markings in Franklin's
books—indicated that the handwriting in the French book did not match
that in Franklin's books. (Source: private correspondence with James Green, The
Library Company of Philadelphia, 27 September 2010.)

[4] The evidence that
Benjamin Franklin (departing from Passy on 12 July 1785 to return to America)
sent a collection of books to Thomas Jefferson (serving in Paris as the
American Minister to France at that time, having recently taken Franklin's
former position there) is that payment for moving these books from Passy to
Paris is included among Jefferson's personal itemized expenses. It is listed by
Jefferson in his ledger as: "portage of books frm. Passy 4 – 4." (The expense is denominated in livres tournois.) This payment was made to "Marc" (last
name unknown), Jefferson's French valet at the time. Marc was first employed by
Jefferson on 20 August 1784 and dismissed from Jefferson's service on 26 June
1786 for "embezzlements and depredations." What little is known about him is
discussed primarily in The Papers of
Thomas Jefferson, Volume 10, edited by Julian P. Boyd, Princeton University
Press, Princeton, New Jersey, 1954, pp. 213-214. The source for the Jefferson
ledger entry described above is: Jefferson's Memorandum
Books—Accounts, with Legal Records and Miscellany, 1767-1826, Volume I, edited by James A. Bear, Jr. and Lucia C. Stanton, Princeton University Press,
Princeton, New Jersey, 1997, p. 590. Jefferson also mentioned his receipt of
Franklin's book shipment in a letter to John Adams dated 28 July 1785 (see The Papers of Thomas Jefferson, Volume 8, edited by Julian P. Boyd, Princeton University Press, Princeton, New Jersey,
1953, p. 317).

[5] The research team has
found no reference to the book De la Caisse d'Escompte in Jefferson's
records of his book holdings. However, other books left by Franklin
for Jefferson on 12 July 1785 likewise do not show up in Jefferson's records.
Specifically, the books from Franklin referred to by Jefferson as "Corps
diplomatique"—probably Jean Dumont's Corps Universel Diplomatique
du droit des gens,…, a set of volumes published in 1726-39—are not
listed in Jefferson's inventories. Nonetheless, in a letter to John Adams dated
28 July 1785, Jefferson acknowledged receiving these books from Franklin. (For
the letter to Adams, see The Papers of Thomas Jefferson, Volume 8,
edited by Julian P. Boyd, Princeton University Press, Princeton, New Jersey,
1953, pp. 315-320. Background on
the Dumont books was provided in private correspondence with James Green,
The Library Company of Philadelphia, 27 September 2010.)

[6] Using temporary
bindings ("interim wrappers") was common in the late 18th century. They were only intended to protect the pages of books until permanent
bindings were applied, whereupon they were discarded. As a result, temporary
covers were sometimes affixed haphazardly, and the external appearance of
temporarily bound books in a given print run could vary.

[7] This caption was
extracted by imaging the type indentations (print through) on the inside of the
front cover and then inverting the resulting image, allowing the backward printing
to be read.

[9] Although we have no
direct evidence that Jefferson and/or Franklin possessed De la Caisse
d'Escompte, we know that both were well acquainted with the author and
owned other books by him. We also know that, in 1785, Jefferson was very
interested in the topics discussed in the book—personally, and in his
role as the American Minister to France. It is highly likely, therefore, that
he would have read it.
